问题描述

当用户单击按钮时，如何使 ImageView 出现在屏幕中间?我已将图像放在 res/drawable-folder 中.

How can I make an ImageView appear in the middle of the screen when the user clicks a button? I have placed the image in the res/drawable-folder.

我一直在尝试使用下面的代码，但我不知道如何使 ImageView 出现:

I've been trying with the code below but I don't know how to make the ImageView appear:

 View v = new ImageView(getBaseContext());
 ImageView image; 
 image = new ImageView(v.getContext()); 
 image.setImageDrawable(v.getResources().getDrawable(R.drawable.gameover));

谢谢！

推荐答案

• 创建ImageView
• 在按钮中使用 OnClickListener
